Hi. Im so frustrated with my phone. Its a samsung j7. The main problem is, i can’t connect to wifi in long range. It became short range. It just happened in a snap. I have to go near to the router so i can have a better WiFi signal. But when im far like 2meters away, its losing its wifi signal. Im sure my phone have the problem coz my other phone can connect and had a great wifi signal even downstairs . Please help me. Been like this since November 2019.
